Tests are accessed and activated in the same way options are selected: by using
the LCD and front panel pushbuttons (as explained in Chapter 3). To find
the LCD screen for a specific test, refer to the LCD flow chart (Diagnostic
And Control Functions) at the end of this manual. Once you access the
screen for a specific test, press pushbutton 1 to begin the test (select ON). A
test status screen is automatically displayed. To deactivate a test, press the
ENT pushbutton and then pushbutton 3. (The ENT button cannot be used to
exit the text screen until the test is deactivated.)
NOTE
For valid test results, error correction must be disabled before diagnostic
tests are run. To disable error correction, set the V.42 Mode option to
OFF.

Modem can be activated via the DTE keyboard using the &T commands listed
in Chapter 5. To set the duration of a test, assign a value to register S18. For
example, AT S18=30 sets the test time to 30 seconds. The command &TO
terminates a test. For further information, see Section 5.2.

remote test initiation or DISABLE to refuse remote test requests.
